How do you naturally increase dopamine levels in the brain?

Dopamine production: There is no proven way to increase dopamine. Ingested Dopamine is broken down in the stomach and small intesting (unless combined with a special medication...Carbidopa, for example in the medicine given to Parkinson's patients carbidopa/levodopa). It can be given intravenously, which is done sometimes to help increase blood pressure. See also: http://en.Wikipedia.Org/wiki/dopamine.
